Re: wiper problem
if you need to know exactly how much pushrod travel you need for a full swipe, put the wiper arm at the bottom of the desired swipe and mark the location of the back side of the wiper arm pivot, under the dash. use a piece of firmly attached cardboard or something held stationary. then move the wiper through the desired arc to the other end of it'd swipe cycle you want it to do. again, mark the spot. now measure how much the pushrod needed to travel in order to acuieve that much wiper arm travel. then do the math and figure out how much you need to change things to get that to work.
